See trees in a different light at Illumination: Tree Lights at The Morton Arboretum. You'll be surrounded by color as you walk a one-mile paved path amid interactive lighting effects that highlight the beauty of trees in winter. Enjoy seasonal music, marvel at ever-changing, interactive lighting designs, and warm up by a crackling fire with a cozy drink or roast marshmallows for s’mores.

This year offers fresh twists on favorite experiences and surprising new sights, including art from HYBYCOZO–amazing treelike sculptures that spread intricate designs of light. Hug a tree to see how it responds, let starlike lights wash over you in a grove of trees, and watch multicolored lights dance to symphonic music.

Insider tip: If you are interested in a less crowded experience, consider purchasing tickets for a weeknight or during the 8:00 p.m. time slot.
